The BigLite EFG series offer these sizes: (as of 1/20/2009)

1. Standard
2. Midsize (+ 1/16)
3. Undersize (- 1/32)
4. Super Jumbo (1.15” diameter)

There is no industry standard in grip sizes. However, based on your hand/glove size, we recommend the following sizing chart:

The above chart is for reference only. We recommend that you talk to a professional club-fitter to help you determine the best size of grips for you.

Both series share the same under-listing (inside tubing).

The EFG series grips are wrapped with a softer polymer surface. This softer surface is preferred by many gofers for its comfortable feel. The EFG series is entirely biodegradable, including the top layer polymer.

The EFG-R series grips are wrapped with a thin rubber skin that provides better traction, a slightly firmer feel and better durability than polymer. However, this thin layer of rubber skin (about 15 % of the weight of the grip) is not biodegradable.

The EFG grips may last more or less than one season depending on the frequency of use.

YES. The BigLite Putter Grip conforms to USGA rules and is approved for tournament play.

The BigLite 1 is 1.70” (43 mm) in diameter and about twice as big as a regular putter grip.

The BigLite 2 is 1.5” (38 mm) in diameter.

The BigLite 3 is a pistol shape grip at about 1.3” in width and 1.7” in depth.

• The BigLite 1 weighs 95 grams.
• The BigLite 2 weighs 85 grams.
• The BigLite 3 weighs 75 grams
• Most regular-sized putter grips weighs between 65 to 75 grams.

The BigLite is 55 - 65 % lighter.

Each 5 gram increase on grip weight will reduce about 1 "swing-weight". Therefore, if your regular grip weighs 70 grams and you switch to BigLite 2, your putter will now feel 3 swing-weights lighter. For example, if the swing weight of your putter was D7, it will now go down to D4. The overall weight of the putter will now go up by 15 grams (less than 3 %).

This change is very minimal for a putter and will virtually give you the same feel weight-wise.

Now consider the switch to a popular Super Jumbo putter grip that weighs 230 grams. At 230 grams, it is 160 gram heavier than a regular grip. Your putter's swing-weight will now be reduced by 80 “swing-weights”. What would that be on a swing-weight scale? The overall weight of the putter will also go up by 160 grams, which translates to roughly an increase of 24%. That is way too big a change in feel!
